hi skieslimit : It depends how toxic you are ,if some one that is highly toxic tries a the big liver cleanse ,they may feel crappy for a week or so ,that is why I chose to do the castor oil packs for a couple of months first, not only that ,but casteroil packs cleanse the lymph system and kidneys as well , the castor oil packs will slowly detox the liver without to big of a shock to the system
it depends how you feel before a cleanse if you feel like your body is strong enough to handle it than go for it , I chose the slower route ,I was pretty toxic at the time ,normaly if you are not to toxic you may feel minor weakness the next day or two ,just depends on how much toxins are pulled out of the liver from the cleanse ( good luck )
